CPT® Code 70300

The CPT® Code 70300 refers to a radiologic examination of the teeth, specifically a single view. This procedure involves the use of various types of dental x-rays to assess the condition of the teeth and surrounding structures. A common type of x-ray used in this examination is the bitewing x-ray, which captures a view of the upper and lower back teeth, allowing the physician to evaluate how these teeth come together, identify any decay present between the teeth, and detect any bone loss associated with gum disease or infection. Additionally, periapical x-rays may be utilized, which provide a comprehensive view of the entire tooth, from the crown down to the root, along with the supporting bone structures. These x-rays are particularly useful for examining conditions that occur below the gum line, such as crowded or impacted teeth, broken tooth roots, abscesses, or other pathological changes. Occlusal x-rays are another type that can be performed, showing the roof and floor of the mouth, and are effective in identifying teeth that have not yet erupted through the gums, extra teeth, cleft palates, jaw fractures, foreign objects, and cysts or abscesses. It is important to report code 70300 for a single view of the teeth, while codes 70310 and 70320 are designated for partial examinations and full mouth series of x-rays, respectively.
